railway 'cars and other-similar vehicles,v

for -theccinfortA ofthe passengers, the fan .or fansv operated by the force of the external encountered by the moving 051e object, amongoth'ers, in producingv :this invention to materially simplify and cheapenthe construction ofmeans for' autoinatically moving the air within a car. This )paratus comprises an -ineased horizontal ful-'heel over the roof of the car the casing having opposite openings `turned in directions longitudinal of the car, for the entrance and i' .t the escape'of the air encountered and passing throughthe casing as the car movesin either direction, means being provided for controlling the intake-of air fori the purpose of regu' lating the rate of the turning ofthe wheel.

Means are also provided for using` the air that enters the casing to the best advantage in. turning the wheel, and for lubricating the bearings vci? moving parts.

The shaft of the wheel pierces the roof of the car, and it is provided at its lower end,

wit'liin 'the car, with a fan to act against the l internal-'air of the car.

.Gth'e'rbbjects and advantages of the invention will be brought out and made to appear. in the following description, and the novel features particularly pointed out in the appended claims, reference being had to the accompanying drawings winch, with the faence characters marked thereon, forrn a y t ofthis specification.

Fig. 2 itral vertical section of the casing and the car, taken. on the dotted hne a in Fig. 3 is a central longitudinal seci the casing and other parts on the i? e E in Fig. 1, parts of the wheel be lly sectioned on the curved dotted d is end-elevation of the cas tri asecciated parte, seen as indicated by arrow c in Fig. 1. Fig. 5 is a view of a hanger for a pinion shaft, and associated parts, look'- ing upward from beneath, the `shaftbeingf horizontally sectioned. Fig. 6 is an elevation of a part of the' Wall of the casing kat one end, seen as indicated by arrow d in Fig. 1 the vertical section being on the dotted line e. Fig. 7 is an elevation of a controlling gate, detached.- Fig.' 8 is a view of parts within the car looking upward from beneath. Fig. 9 is a side-elevation ofthe casing and adjacent portion of a car, seen as indicated lubricating cup uncovered, showing the end of the wheel shaft. hub and parts of the wheel, showing the oil ducts, the shaft being `transversely sectioned as on the dotted line in Fig. 3. Fig. 1 2 is a 4vertical section ofparts through the axis of the wheel and shaft, further showing the loil passages to the bearing of the shaft. Fics. 4, 5, 6, 7, 10, 11 and 12 are drawn to sca es larger than that of the remaining figures.

Referring to the parts shown 1, Fig. 9, is a portion of the upper part of a c ar-npon the roof 5 of which is mounted a metal casing 2, Figs. 1, 23, 4. and 9, inclosii'ig a driving wheel 3. This Wheel is 'carried by a vertical shaft 4, Figs. 1, 2, Sand 8 to 12, piercing the roof 5 of the car and carrying at its lowerend within the car a' fan 6. The casing 2 is formed alike at both ends, having similar flaring mouths or openings 7 ing in opposite directions, and being mounted longitudinally upon the car with the openings facing toward the respective ends of the car. vThe wheel 3 is formed with peripheral radially upon the band or body 9 of the direction toward the right,regarding Fig. 1, the air entering the mouth or opening 7, as .indicated by the full-linearrow, will impinge against the buckets 8 inv its path and turn the Wheel as indicated by the curved ar' row and finally pass out at'the opening 7', as indicated. 0r, if the car be moving inthe opposite direction the encountered air will pass in at the mouth or opening 7', indicated bythe dotted arrow, and out at the mouth 7., the wheel always being turned by the air in the same direction.

it will be observed that 'the opposing vcrtical side walls of the casing 2 are eachV com- 1Q the straight parts .being parallel and long'iv 'by arrow f in Fig. 1. Fig. 10 is a plan of the Fig. 1'1 is a plan of thel 7 turned or facwheel, as shown; and, if the car be moving in:

posed of asti'aight part 27 and a circular'part buckets 8, Figs. 1 and 2,' preferably disposed tudinal of the car and the curved parts concave toward each other with the wheel 3 be tween, said curved portions l being eccening the inner surfaces of the curved walls 10.

This permits of portions of the inflowing air to pass the edges of the buckets first encountered and so strike with force the buckets further on, thus using the moving airxto the best advantage for turningr the wheel.

Gates 12, Figs. l and `7 are employed 'to control the amount of air iowing into either mouth of ,the casing, for the purpose of regulating the velocit of the wheel, the gates turning on vertica pintles 2 3 held by the casing. These gates are operated by means of horizontal toothed racks 13 moving in guides 18, Figs. 1 3, 4, 8 and 9,

or rests 14, Figs. 1, 3, 4 and 9, secured to the4 curved parts of the casing 2, the racks entering the casing through openings 15, Fig. 6, and piercing the gates 12, at 16,Fig. 7, and being movably attachedthereto. The racks are moved longitudinally by pinions 1T held between branches of the rests 14, the plnions being carried by vertical spindles or shafts iercing the rocf of the car and having knurlled ears or thumb` pieces 19 for turning them.

The shafts 18 pass through .hangers 20 pending from the roof of the car, and holding split clamps 21, best shown in Fig. 5, pierced by the spindles, clamp-screws 22 being pro.

vided for tightening the clamps onto the spindles. By these means the gates 12 ma 'i be shifted and set in any positions desire turning on the pintles 23 rigid in the upper plate and the floor of the casing.

In using this apparatus the gate 12 of the .f discharge opening of the casing is fixed Wholly open, as 'appears at the left in Fig. 1,

the gate at the intake opening being setto `regulate the amount 'of air passing intatte eas' 1n any given case;

The -shaft 4 holding the-Wheel 3 -is formed with an enlarged part'24, Figs. 3 and 12, be-

low the hub of the wheel, resting at its lower end upona suitable bearing on the iioor or lbottom plate of the casing, which' bearing may be provided with'balls ory other antifriction devices in common luse.` 0n theupperside of the casing 2 is' providedan oil cup or.

reservoir 25, Fi s. 2, 3, 4', 9 and f10, vfor holding saturated f1 er as cotton waste, ducts or passages 26, Figs."10, 11 and 12, being formed in the shaft to conduct the cillto the, bearing of the shaft at the floor` ofthe casing.,V

What I claim as my invention andjdesirev to secure by Letters Patent is l 1. A device for Ventilating cars,kcon'iprly's-v ing a casing on the car having airpassages at opposite ends and its opposing side-walls'.

having curved portions concave toward'each other, and a Wheel between and eccentgic with said curved portions, a shaft for the wheel extending into the interior of the car, a

fan on the shaft, and means Vwithin the said.

air passages for controlling the amount of air acting against the wheel and independent means for actuating the'-means at each "end independently of the other,

2. A device such as described, consisting of a casing without the car having air opens ings, a wheel in the casing, a shaft for the wheel extending from without to within the car, afan on the shaft within the car, ivotal gates for controlling the flow of air Wit in the casing, toothed racks connected movably with the gates, guides onthe casing for the "racks, toothed pinions in the guides to engage the racks, and means Within the car for turningthe pinions. v

In Witness whereof, I have hereunto set my' hand this 8th day of August, 1907, inthepresence of two subscribing witnesses. l GEORGE W. p RUGGLES. Witnesses:
